Railway car side construction

ABSTRACT

A railway car side includes a plurality of vertically extending horizontally spaced posts of hat-shaped configuration connected to corrugated stiffener panels supporting outer sheathing. The corrugated panels have end portions extending adjacent to flanges of the hat sections and are connected to the posts by means of flanged brackets which extend diagonally from the webs of the hat sections to the corrugations.

INVENTORS THOMAS O'NEILL NORMAN M. SZALA WILLIAM VAN DER SLUYS RAILWAYCAR SIDE CONSTRUCTION SUMMARY It is the primary object of this inventionto provide an improved side construction for a railway car of thepassenger or transit type. It is a common practice in the constructionof railway car siding to utilize sheathing which may be of a thinstainless steel or aluminum construction. The sheathing is generallyreinforced by means of inner corrugated panels disposed between verticalposts horizontally spaced along the sheathing of the car. In many typesof construction corrugations have been directly attached to the verticalposts. This type of connection has in many instances caused buckling ofthe sidewall sheathing thereby precluding the smooth surface which isdesired. The present construction provides a manner of connecting thecorrugations to the posts by the utilization of formed brackets whichwill prevent the sheathing from developing an offset and thus assuringan effective and smooth outer surface. This is achieved by theutilization of a hat section for the post which comprises outer flangesconnected directly to the sheathing by welding or other means. The innerstiffener corrugated panels are temiinated at the ends of the flangesand are connected to the post by means of the formed brackets whichextend from the webs of the hat-shaped section diagonally and areconnected to the corrugated panels by means of flat flange portions.This manner of connection prevents the development of the deficienciesfound in the conventional construction referred to hereinabove.

BRIEF DESCRIPTION OF THE DRAWINGS DETAILED DESCRIPTION A transit orpassenger car side is generally referred to by the reference character10, and includes an upper longitudinally extending Z-shaped stringer 11and a Z-shaped stringer 12 which is disposed approximately midwaybetween the upper and lower ends of the side 10. The side 10 includes alower side sill 13 which may be of a boxlike construction. The skin orsheathing for the side 10 is designated generally at 14 and comprises anupper panel 15 provided at the upper end of a window opening 16 which isdisposed between the Z-shaped stringers l1 and 12. A plurality ofvertical posts generally designated at 17 are horizontally spaced alongthe side 10 and each comprises an inner vertical wall 18 connected tovertically extending webs 19 extending outwardly from the wall 18 andincluding flanges 20 in hat-shaped configuration. The flanges 20 areprovided with coextensive lips 21 projecting inwardly from the sheathing14. The upper extent of the side 10 is also provided with a portion of aroof sheet 22 as indicated in FIG. 2.

The skin or sheathing 14 further comprises a lower side sheet 23 whichis substantially flat at its lower portion and includes an uppercorrugated portion 24 suitably connected at its upper ends to thesheathing l4 and the Z-shaped stringer I2 underneath the window opening16.

As best indicated in FIGS. 2 and 3, the lower side sheet 23, in theregion disposed below the window opening 16, is provided with corrugatedstifi'ener sheets or backing plates 25 having a plurality ofhorizontally or longitudinally extending corrugations 26. Thecorrugations 26 as shown in FIG. 3 terminate slightly short of the lips21 and are connected to the vertical posts 17 by means of stiffenerbrackets 27. Each stiffener bracket 27 comprises an intermediate plateportion 28 having at opposite ends thereof flange portions 29 and 30.The flanges 29 of the stiffener brackets 27 are connected to the webs 19and the plate portion 28 extends diagonally toward the corrugations 26.The flange portions 30 are connected to the corrugations 26 and areprovided at their ends with inwardly extending lips 31. While thebrackets 27 have been shown as short individual units, it iscontemplated that they may run the length of the posts if desired. Asbest shown in FIGS. 1 and 2, the sheathing 14 extending laterally fromthe window opening 16 is also reinforced by a suitable corrugatedreinforcing sheet 32.

As indicated in FIG. 3, the connection of the corrugations 26 to thelower side sheet 23 may be made by welding, the flanges 20 providing aflat attaching surface. The ends of the corrugations 26 in turn areconnected to the posts 17 by means of the stiffener brackets 27 bywelding. By virtue of the connection of the stiffener brackets 27 to thehat-shaped flanges 20 and to the corrugations 26, the possibility ofdeveloping an offset in the skin 14 or lower side sheet 23 is eliminatedand yet an effective supporting arrangement for the sheathing 14 isprovided.

Thus the objective of the invention has been disclosed and described andthe scope thereof is defined in the appended claims.

1. A wall structure comprising:

a plurality of laterally spaced posts,

each post having a U-shaped configuration including an inner wallconnected to parallel webs projecting outwardly with respect to saidinner wall,
